15 years ago, i suffered a head injury. the frontal lobe of my skull was removed, repairs made and it was replaced. i have had little or no problems until two days ago. i now feel pressure on my forehead. i have also had ringing in my ears?

Head trauma: Please see your doctor who may refer you to a neurologist. Please do not jump to conclusions because these symptoms may not be related to your previous positive response to surgery. Peace and good health.

Emergency care: You may have a sinus infection, but given your history, I would advise seeing the Emergency department and calling your PCP.
